CONNECTING-ROD FOR SWITCHES.

SPECIFICATION forming part of Letters Patent No. 398,102, dated February 19, 1889.

Application filed December 6, 1887. Serial No. 257,160. (No model.)

To all whom it may concern:

Be it known that I, FREDRIC C. \YEIR, a resident of Cincinnati, in the county of Hamilton and state of Ohio, have invented certain new and useful Imprevemen ts in Connecting-Rods for Switches, of which the followingis a specification.

The object of my invention is to provide effective means for uniting the connecting rod to the switch-crank and switch-rail in such manner that they cannot be tampered with, or detached, or accidentally displaced, all of which will be fully explained in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 is a top plan view of my improvement; Fig. 9, an elevation showing the-switchstand and the rails in section. Fig. 3 is atop plan view of the coupling-box. Fig. 4 is a side view of the same. Fig. 5 is a diagram showing the coiniecting-joint.

1 represents the main rail 01' the track; 2, a split switch-rail; 3, a chair connecting the switch-bar to the split switch-rail.

4 represents the switch-bar.

5 represents theconpling-box. This coupling-box is made of two sections, as shown in Fig. 4-, and united by means of the rivet o and pivot-bolt 7, extending through the slot or opening 8.

9 represents ribs for strengthening the coupling-box.

10 represents the connecting-rod, the end 11 of which is made large or circular, as shown in Fig. 5, and it is provided with a slot, 12, sufficiently large to engage over the pivot-bolt 7. When the connecting-rod is turned around at right angles to its normal position, (shownin Fig. 5,) the slot 12 allows it to be released or engaged over the pivot-bolt '7. The periphery 13 of the slot provided in the coupling-box prevents the hook of the connecting-rod 10 from being released until. it has been turned to the position shown.

14 represents the base of the switch-stand; 15, the crank-rod; 16, the cap of the journalbox, 17, bolts for attaching the same.

The parts are connected as follows: The switch-bar is first connected to the switchrail and the coupling-box securely riveted thereto. The connecting-rod 10 is then engaged upon the pivot-bolt 7 and turned around to its normal position. (Shown in Figs. 1 and 2.) The cap of the journal-box 10 is then released or taken oil and the switch-rod 1.8 raised up until the end of the crank-pin is raised sufiiciently to be engaged with the eye of the connecting-rod 10, when it is allowed to enter the eye. The pivot and connecting-rod rest on the base 14 of the switch-stand, preventing the parts from being accidentally displaced and rendering it diffieult to tamper with the connecting-rod.

Having described my invention, what I claim as new is- 1. In combination with the switeh-stand and crank, the connecting-rod 10, provided with a circular end, 11, having the slot 12, and the coupling-box 5, provided with the pivotbolt 7, attached to the switch-bar, substantially as specified.

2. A connecting rod and joint composed of the coupling-box 5, provided with the circular slot and pivot-bolt 7, the connecting-rod 10, provided with the enlarged end 11, and the slot 12, to engage over the pivot-bolt, substantially as specified.

In testimony whereof I have hereunto set my hand;

FREDRIC C. WEIR.
